To all whom #may/'concern v Be it known that I, PETER J. Jcncirnm a fcitizen of the 'United States,"aiid resident of Sheboygan Falls, in the county of She.-

' Feeders for Planers, ofwhichthe follow- 'Y part of this specification; Y

ing is ,a description, reference being had to the accompanying drawings, which areja This invention relates Vto feeders Yfor planing machines and has for its object to provide a feeder in which the feed rolls lare located close together without the presence of supporting frames' between thenn'such rolls being independently niount- "ed vsoas to rise or fall or tilt in either directionwith the irregularity of the surface `of-the work operated upon, reinainingin positive driving connection throughout such 'movements to effect the feeding of the work ers as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in the differentviews: Figure 1 is a plan view of a feeder for planers constructed in accordance with this invention; Fig. 2 is a side view there-of; Fig. 3 is an end view thereof sho-wing the ability of the feed rolls to adapt themselves to irregularities in the surface of the work; and, Fig. 4. is a sectional view of one of the feed rolls.

In these drawings 10 indicates a frame which may be ofy any desirable form or construction and which is preferably a rectangular casing as shown. A shaft 11 is journaled through the frame and has sprocket wheels 12 fixed thereon for driving the feed rolls by means of chains 13. The feed rolls 14 are preferably of solid metal to give them the desired weight, though they may be of other construction and each is provided with a central opening within which loosely fits a core 15. Each feed roll 14 has its own core 15, but the feed rolls of each row, of which there may be two or more, have their cores 15 vertically slidably mounted on cross bars 1G extending across the frame. These cross bars 16 are flat so as to prevent the turning of the cores 15 and fit in slots 17 which extend upwardly from the lower Specification of Letters Patent.:

the chains.

edge .0f the 001'@ und are somewhat shorter thanthey said slots so that thecoresare free Ato move vertically on the cross rods and the -turning of the feed rolls on the cores does not interfere with the up and down movement of thefcores. The feed rolls themselves are thus permitted to rise and* fall: independently of each other while being turned by the chainsV passing aro-und grooves in lthe face thereof, which vgrooves are provided with sprocket teeth 18 for engagementv with row farthest froni the shaft 11 have the ference, buty the feed rollsV in the intermefdiate row have the chains engage their sprocket teeth at the top and bottoin thereof. The cro-ss bar 16 of this intermediate row of feed rolls, because of this engagenient of the sprocket teeth above and below with the drivingchains, doesnot reduire the i presence of means for holding it in a 'definite position as to its distance from the shaft 11 andv this cross rod is therefore freely slidable at its ends in slots 19 at the sides of the frame, but the cross bar of the end row of feed rollsrequires to be held in fixed position with relation to the shaft 11 in order that the driving chains inay be kept tight and in engagement with the sprocket teeth of the intermediate ro-w of feed rolls and while this cross bar has its ends Slidable in slots 19 of the sides of the frame as with the other, it is fixed in position by having set screws 20 threaded therein, said set screws freely turning through lugs 21 projecting from the sides of the frame at the ends of the slots 19. The set screws 20 are locked in their adjustments by means of latches 22 which are pivotally mounted on the sides of the frame and are adapted to be swung into position between the side of the frame and the flat sideof the square head of set screw 20 and prevent further turning of said set screw, the latch being provided with a spur 23 to engage the lug 21 and hold it in its locking position.

In operation the feed rolls .are all hidden K and by reason of their slidable cores they are permitted to follow the irregularities of The feed rolls which are in thel i 'l Patented Feb. 1'5, 1916. Application sied oetber ii, i912. sei-'iai No. 725,135. i y

the surface of the work, rising and falling with a change in thickness of the work and v inclning to the right or left when the work iio is of a tapering thickness as indicated in Fig. 3. Thus instead of the feed rolls hav-l ing single points of contact with thework feed rolls being mounted together side byside on the cross bars without swinging frames between them to space theml apart there is no danger of a small strip of work iinding a position beneath the feed rolls where it does not come in contact therewith and consequently there is no danger of such small pieces of work being thrown back by the cutters to injure the operator. Several pieces of work of different thickness may be fed to thecutters at the same time, the feed rolls adjusting themselves to the thickness of the work engaged by them in such a manner that the thin pieces of work as well as the thick pieces of work are positively driven. Y

What I claim as new and desire to secure by Letters Patent is:

l. A feeder for planers, comprising a frame, a pair of parallel cross rods thereon angular in `cross section, a series of slotted cylindrical cores slidably mounted on the cross rods to have vertical movement thereon, a series of feed rolls, each rotatably mounted ron one of the cylindrical cores, sprocket teeth Aformed in a groove in the center of the l.face of each of the feed rolls, a suitably driven shaft on the frame in the plane of the-cross rods and parallel there- Copies of this patent may be obtained for ve cents each, by addressing the -f Commissioner of Patents,.

with, sprocket wheels mounted on'. the shaft,`

chains connecting the sprocket wheels with the sprocket teeth ofzeach ofthe feed rolls, the chains passing from the sprocket .wheels around the feed rolls on the cross rod whichl is farther from the shaft and engaging :the

sprocket teeth of the other feed rolls in such passage, said cross rods-being slidable in.

the frame toward or away from :the shaft,` and means for sliding the cross rod lwhich 1s' farther from. the shaft to adjust the tension:l

v of the chains. f

V2. A feeder for Iplaners, comprising a frame, a suitably drivenA shaft thereon,` sprocket wheels on the shaft', chains passing,

around the sprocket wheels, cross lrods slidably mounted across ,the frame in slots. thereof, slotted cylindrical cores slidably4 mounted ,on the cross rods, feed rolls rotatably mounted on the cores and provided w-ith sprocket teeth engaged bythe chains, ears on the frame, set screws passing through the ears and threaded ini the cross rod ofthe feed rolls which are farther from .the shaft` for adjusting the cross rod in the slots of the frame to tighten the chains,'and la latch pivotally mounted on theframeadapted to` fit between. the head of the set screw and the side of the frame to lock the set screwin its adjustments.

In testimony whereof, I :ali'ix my signature, .in presence of two witnesses.
